High-Temp Salt-Resistant Fluid Loss Reducer

  • Solving fluid loss in medium-deep high-temp wells.
  • CPK resists 180°C+ and 15% salt+1% gypsum, 5% aqueous viscosity ≤8mPa·s, reduces HTHP fluid loss to ≤35ml.
  • Ideal for cost-sensitive drilling projects.

Main Advantage & Solution

  • 1: High temp (180°C) increases mud viscosity;
    Solution: 5% aqueous apparent viscosity ≤3.5mPa·s, no viscosity buildup in mud.
  • 2: Multiple additives cause formula complexity;
    Solution: Integrates fluid loss control and stability, simplifies mud formula to reduce costs.
  • 3: Salt contamination degrades sealing performance;
    Solution: Resists 15% salt+1% gypsum contamination, stable in complex mud systems.
